Test after JDK-8181761, the explicit @build actions

[Weijun Wang]

Hi Igor

I’ve about to add a new test that uses jdk.test.lib.SecurityTools and I see in 
your fix for JDK-8181761 that a lot of seemingly-unrelated classes are added 
into a @build action.

How do I determine what classes are needed? Or shall I just copy it from a test 
nearby?

I remember this was due to a jtreg bug(?). Has it been resolved? Do we need to 
add the @build action forever?

Thanks
Max
